| Research Abstract |
The quantitative determinations of active ingredients of wood preservatives in treated wood are important to guarantee protection. Organic active ingredients are extracted from treated wood with organic solvents, such as methanol, and then analyzed using high-performance liquid chromatography (HPLC). However, it was expected that co-extracted wood components interfere with the HPLC analysis of the active ingredients. In the case of triazole biocides, co-extracted wood components interfere with HPLC analysis with UV detection. The interfering components could be removed from sample solutions by solid-phase extraction (SPE) using strong cation exchanger. The SPE method could be used for removed interfering components of wood specimens exposed in soil. Quaternary ammonium compounds could be quantified using HPLC with evaporative light scattering detection (ELSD). In this case, co-extracted wood components did not affect the HPLC-ELSD analysis. This method could be applied to the determination of the quaternary ammonium compounds in wood specimens exposed in soil.
